Question

if a+b = 2 and a-b = 4 then find the value of a^2 + b^2 ?​

Answer 1

Answer:

10

Step-by-step explanation:

a+b = 2 ------- (i)

a-b = 4 ------- (ii)

subtract (ii) from (i)

therefore

2b = -2

b = -1

apply this in equation (i)

therefore

a-1 = 2

a = 3

_____________

Hence,

a = 3

b = -1

3² + 1²

=9+1

=10
